+ * Coordinates download parameters and manages their dependencies
+ * prior to downloading them.
+ *
+ * Input can come from three sources:
+ *
+ * - local files (archives or package.xml)
+ * - remote files (downloadable urls)
+ * - abstract package names
+ *
+ * The first two elements are handled cleanly by PEAR_PackageFile, but the third requires
+ * accessing pearweb's xml-rpc interface to determine necessary dependencies, and the
+ * format returned of dependencies is slightly different from that used in package.xml.
+ *
+ * This class hides the differences between these elements, and makes automatic
+ * dependency resolution a piece of cake. It also manages conflicts when
+ * two classes depend on incompatible dependencies, or differing versions of the same
+ * package dependency. In addition, download will not be attempted if the php version is
+ * not supported, PEAR installer version is not supported, or non-PECL extensions are not
+ * installed.
